Abstract
An improved method for making a decision on choosing the best self-propelled sprayer from alternative options is proposed. It refers to new developments in various fields of environmental monitoring and analysis of field self-propelled sprinklers, but which substantiate the studied factors characterizing each unit. The factors are taken with real values of calculated parameters, for which the desirability function and weighty coefficients are developed using the method of pairwise comparison of calculated parameters of absolute and relative rank places and the percentile function. The dependence of the transfer of calculated parameters of the unit from real values to dimensionless ones for the y’ scale is clarified, according to which the desirability function is calculated, and then a generalized parameter characterizing the complex evaluation of the unit in respect to the weighting coefficient of each estimated parameter. The decision is made according to the maximum value of the parameters of integrated assessment of the sprinkler, in this task for the sprinkler TUMAN-1 (Russia), for which the value of the parameter of integrated assessment is obtained.
